From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

su is the best. I mean, i should be using the admin (root) password for admin things, not the user password of user who is already logged in. And there needs to be a root service already running to make user have root previlages which is dumb imo. Sudo vulnerability could cause previlage escalation but if there is no root process managing this, then it can't leak the root access. Only kernel security issue(or other root processes) will leak root access if that was the case, which i think is better.
The permission to do admin things is given by the root user, to your account. So you have to verify your identity by entering your password.
Isn't that how it is? I though that was analogous to how almost everything worked IRL. Whether withdrawing funds from a bank or engaging government services, you prove your identity as a customer/citizen to get the relevant services. At no point do you login to bank or government computers with full privileges.
If you own your own bank, then i think you login as the one with full previlages. Yes when doing administrator things, you have to use sudo. The problem with root with sudo is, you authenticate as a user, then gain full permission from root, i.e analogous to login in to bank with full previlages.
As a person who need to run
sudo commandits better to just verify yourself as root user to gain "full access". I'm not saying about partial previlages. That is i just need a script which is just su -c with environment variables being copied
